T106125 90uH Magnetic Ring Inductor High Current Ring Inductor Common Mode Coil
1.Product Description
90uH Magnetic Ring Inductor, also known as High Current Ring Inductor or Common Mode Coil, is a highly specialized passive electronic component. With an inductance value of 90 microhenries (uH), this magnetic ring inductor is designed to handle high - current applications while efficiently suppressing common - mode noise. Its toroidal core, usually made of high - permeability magnetic materials like ferrite, provides a closed - loop magnetic path that minimizes magnetic flux leakage, enhancing energy storage and conversion efficiency. In high - current scenarios, it maintains stable inductance performance, ensuring smooth current flow and reducing power losses. As a common - mode coil, it plays a crucial role in filtering out unwanted common - mode interference signals in power lines and signal transmission cables, improving the electromagnetic compatibility (EMC) of the circuit. This makes it widely applicable in power supplies, motor drives, communication systems, and other electronic equipment, where both high - current handling and effective noise suppression are essential for optimal system operation.Here are some of the main application areas:
1. Power circuit: It can be used for filtering and energy storage in various power adapters and switch mode power supplies. As an energy storage component, it can stabilize the output current and ensure the stability of the power output when the input voltage fluctuates or the load changes. At the same time, it can effectively filter out high-frequency noise in the power supply, reduce power ripple, and provide pure DC power for the backend circuit. For example, in computer power supplies, it can help stabilize output voltages such as 12V and 5V, reducing the impact of voltage fluctuations on computer hardware.
2. Motor drive circuit: In industrial motors, automotive motors, and other drive circuits, this inductor can be used to limit the rate of current rise and prevent damage to the circuit caused by surge currents during motor start-up. In addition, it can also suppress electromagnetic interference generated during the operation of the motor, improving the reliability and stability of the motor drive system. For example, in the motor drive system of electric vehicles, it helps to protect power devices and reduce the impact of electromagnetic interference on onboard electronic equipment.
3. Communication system: It can be used for impedance matching and filtering in RF circuits of communication devices such as mobile phones and base stations. By selecting the appropriate inductance value, efficient transmission of RF signals can be achieved, reducing signal reflection and loss. At the same time, it can filter out clutter signals within the communication frequency band, improving signal quality and the anti-interference ability of the communication system. For example, in the antenna matching circuit of a mobile phone, it helps optimize the radiation efficiency of the antenna and improve the communication performance of the phone.
4. Electromagnetic compatibility (EMC) design: In the EMC design of electronic devices, as a common mode coil, it can effectively suppress common mode interference current. When the device is subjected to external electromagnetic interference or internal electromagnetic interference, the common mode coil can convert the common mode interference into differential mode interference, and then filter it out through a filtering circuit, thereby improving the electromagnetic compatibility of the device and meeting relevant electromagnetic radiation and anti-interference standards. For example, in industrial automation equipment, it can prevent the equipment from generating electromagnetic interference to the surrounding environment, while improving the equipment's own anti-interference ability to ensure stable operation in complex electromagnetic environments.
2.Performance Characteristics
| Performance Characteristics | Details |
| High Inductance Value | With an inductance of 90uH, it provides strong inductive reactance, effectively suppressing current changes. Ideal for circuits requiring stable current output, it presents high impedance to high - frequency signals in AC circuits, enabling excellent filtering performance. |
| Stable Inductance | The toroidal structure forms a closed magnetic circuit, minimizing magnetic flux leakage. This ensures the inductance value remains stable under various operating conditions, guaranteeing consistent circuit performance. |
| High Current - Carrying Capacity | Designed as a high - current inductor, it uses low - resistance, highly conductive wires for windings, reducing heat generation and power loss. The magnetic core material has a high saturation flux density, preventing saturation even under large currents and maintaining normal operation. |
| Effective Common - Mode Noise Suppression | As a common - mode coil, it excels at suppressing common - mode interference signals. When common - mode interference currents pass through, the magnetic fields on both sides of the magnetic ring stack up, creating high impedance for common - mode signals and attenuating them. Normal differential - mode signals are hardly affected as the magnetic fields on both sides cancel each other out, enhancing the circuit's EMC. |
| Compact Design | The toroidal shape offers a compact form factor, occupying less space on the circuit board compared to other inductors. This makes it suitable for integration into miniaturized and high - density electronic devices. |
| Cost - effectiveness | Thanks to mature manufacturing processes, magnetic ring inductors are cost - controllable. They can meet multiple performance requirements while maintaining high cost - effectiveness, making them applicable to a wide range of cost - sensitive electronic products and industrial applications. |
